IMPROVED GAR-GOUPLING.

TO ALL WHOM IT MAY CONCERN:

Be it known thatI, HENRY B. HOWE, of the town of Hartwick, in the county of Otsego,and State of New York, have invented a new Self-Acting Car-Coupling; and I dohereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a perspective view, 7

Figure "2 a. longitudinal view through the centre, showing both the internal and external arrangements of .the several parts which compose this invention.

Same letters refer to corresponding-parts in each of the figures.

The nature and design of this invention are to construct a. car-coupling that will couple whenever the cars are run togpther, without the necessity of any person going between them to put in the link and pin, and thus save time and prevent accidents. I i i A is the bufier, and is constructed hollow and flaring at the front end, so that the lihk will be certain-to strike inside the mouth as the cars are brought together, and he conducted to the centre, where it strikes a .block, which it causes to retreat, thus coupling the cars.

B B are the cross-beams, by which the bufi'er A is secured to the cars. 0 is a. block on the car to support the end or rod Den the rear end of the bnfier.

E is a block, which is constructed to operate in a suitable hollow cavity inside the buffer A, and has a slot cut therein, through which a pin passes to keep it in the desired position, and allow it to operate-the required distance. v

G is a coiled spring in the cavity of the bulier, behind block E, to operate it.

I is the link by which the cars are connected.

J is the pin which passes through the link, connecting it to the car,

K is a spring-plate, one endof which'is connected to the head of the pin J, the-opposite end being con nected to the butter A.

L is a lever, of any'suit'able shape, which is connected to the spring-plate K, extending across under the platform the entire width of the ear, in order that it may be used from either side.

' M M are small rods, secured to the car, passing through slots in the lever L, to keep it in the required position. h I V N is a tongue, in the mouth of the buiier, to hold the link in the right position to be attached to the other our, and it is attached by hinges.

O is a spring-bar, under the buffer, which assists in holdingup the pin J, the end of said spring being' turned up through the link I, to prevent lateral deflection when said link is attached to only one car. This spring is constructed to operate perpendicularly or horizontally in crder'to allow the link to turn sufliciently to accommodate itself to any curve or unevenness of the track. v i

P is a bar connected to spring 0, the erid of whichis turned up under the tongue N, which it holds in the required position. i i l R is a small chain, connected to the tongue N and bar P, to depress said tongue by means of the lever L.

S is a sct scre'w, by which the height of the tongue is adjusted, which may be made to operate against either the spring-bar K or the butter A. l i

T is the pin through the block'E, on which it operates.

To use my invention, the lever L should be depressed, which, drawing out the pin J, and freeing the link I, uncouples the cars, and when lever L is lowered suificiently to enable the spring G to force out the block E, it will prevent the pin J from passing into its place, while the chain R draws down the tongue',.l eaying the mouth of the buffer A open, so that when the link of the car to be attached comes inside it will be guided to the centre, and its end striking against the block E forces it back, and the springs O and K force the pin through 80,486 2 the link and securely attach it to the car, may meet. I

This couplixig can be constructed with only one spring, but I prefer two. What I claim as my invention, arid desire to secure by Letters Patent, is

The combination of the buffer A, spring-bars O and K, bent bar P,'cha.in R, tongue N, blbck E, pin '1,

spring G, link I, pin J, set-screw S, and lejver L, .when; constructed and arranged substantially as described, as and for the purpose specified.-

The block allows the link suflicient playin order that the buffers Witnesses: SAMUEL IIAnPER, HIRAM TUTTLE.
